Autoclaved aerated concrete block (AAC), popularly called lightweight concrete, is an environmentally friendly building material that has been used widely in Europe since the 1920s.
No AAC application is one size fits all. It is important to talk with a speech pathologist about the pros and cons of any AAC app and to find one that meets your individual needs. This article is intended to be a reference as to features that Proloquo2go contains that may be helpful for successful AAC use.
AAC was developed in 1924 by a Swedish architect, who was looking for an alternate building material with properties similar to that of wood – good thermal insulation, solid structure and easy to work with – but without the disadvantage of combustibility, decay and termite damage.

AAC Blocks ensure rapid construction because of it's big size, easy to cut in any shape or size and light weight. AAC blocks covers areas of 24" x 9" whereas the red bricks cover only 9" x 4" area. Hence fewer joints results in considerable fast speed construction.
The best benefits of AAC block in a Low rise structure (less than G+5 construction) is sound proofing and thermal insulation. If you require these properties in your brick then go for AAC block. Otherwise economically red clay brick (Class A) or fly ash brick is a better option.

Issues with Aerated Autoclaved Concrete (AAC) Dr. Nabil Taha has over 27 years of structural engineering experience. Prior to opening his own engineering firm in Oregon in 1997, he was a Professor of Engineering at Northern Montana State University and at Oregon Institute of Technology.
Autoclaved Aerated Concrete (ACC) Autoclaved Aerated Concrete (ACC) is a thermally insulated concrete based material. It is used in both internal and external construction. This is relatively a new product that is being integrated into the construction process.
Autoclaved aerated concrete, or AAC, is concrete that has been manufactured to contain lots of closed air pockets. Lightweight and fairly energy efficient, it is produced by adding a foaming agent to concrete in a mould, then wire-cutting blocks or panels from the resulting ‘cake’ and ‘cooking’ them with steam (autoclaving).
Finally, AAC is beginning to catch on in the United States, where there are now three AAC manufacturing plants with several more planned. This represents a serious commitment since the cost of a plant to produce AAC blocks and panels is between $30 and $40 million.

The Scandinavian countries have timber, as do other countries, but there simply aren't forests massive enough to supply the continent. (And of course, in the Mediterranean countries the forests were decimated centuries ago.) So they use masonry: a lot of bricks, stones, and blocks. AAC is a greatly improved kind of block, with a lot of advantages.
